postgres - cannot drop database using psycopg2

So I simply trying to drop and recreate my database using Python's psycopg2. Here is my code:

    with psycopg2.connect(database="postgres", user="postgres", password="****") as conn:
    with conn.cursor() as cur:
        conn.autocommit = True   #  Explains why we do this - we cannot drop or create from within a DB transaction. http://initd.org/psycopg/docs/connection.html#connection.autocommit
        cur.execute("DROP DATABASE crowdsurfer;")
        cur.execute("CREATE DATABASE crowdsurfer;")

When I run this code, I get

PS C:\Users\Nick\Documents\GitHub\CrowdSurfer\CrowdSurfer> python utils/sqlInit.py
Traceback (most recent call last):

  File "utils/sqlInit.py", line 70, in <module>
    run()

  File "utils/sqlInit.py", line 21, in run
recreate_empty_database()

  File "utils/sqlInit.py", line 40, in recreate_empty_database
    cur.execute("DROP DATABASE crowdsurfer;")

psycopg2.OperationalError: database "crowdsurfer" is being accessed by other users
DETAIL:  There is 1 other session using the database.

Alright, fair enough. So I opened a connection to postgres and took a peek at the existing processed before and while my code was running. Before my code started, we get this:

postgres=# select pid from pg_stat_activity

This command returns a single PID, PID 6052

This process is me, so that's good. Now here is what I get when query running processes while my python code is running:

 postgres=# select * from pg_stat_activity;
 datid  |   datname   | pid  | usesysid | usename  | application_name | client_addr | client_hostname | client_port |       backend_start        |         xact_start         |        query_start         |
       state_change        | waiting | state  |                         query

  12029 | postgres    | 7908 |       10 | postgres |                  | ::1         |                 |       49851 | 2014-03-11 23:14:57.556-06 | 2014-03-11 23:14:57.559-06 | 2014-03-11 23:14:57.559-06 |
2014-03-11 23:14:57.559-06 | f       | active | DROP DATABASE crowdsurfer;
(3 rows)

The python code started 2 processes! One connects to the postgres DB, which I did explicitly. The other connects to the DB I want to delete (crowdsurfer). Note that it is idle, and the query it ran was SET default_transaction_isolation TO 'read committed'

So it seems like setting conn.autocommit equal to true is creating a new process??? Any thoughts on what to do here to make drop this DB?
